FIGURE 5.6 DC AUXILIARY RELAY TIMING TEST
NOTE: The external start timer mode is intended to be used when there’s a separate signal used to start
the timer which is different from the fault initiation signal or event.
If external start timer mode is used, and the external start trigger signal also triggers the fault,
fault incidence angle control must be set to random (off), since the combination of these
conditions is invalid.
The external start timer mode can be used to time secondary and auxiliary relays in a relay system where
the applied inputs to the system under test must operate a primary relay first, before the relay of interest is
operated. An example of this is shown in Figure 5.7.
